Engineering a bosonic AdS/CFT correspondence

TL;DR

This paper explores a non-supersymmetric bosonic string/gauge theory correspondence by constructing stable AdS solutions and analyzing their implications for a 12-dimensional boundary conformal field theory, extending AdS/CFT to finite temperature.

Contribution

It proposes a novel bosonic AdS/CFT correspondence with a stable AdS_{13} x S^{13} solution and explores its implications for a 12-dimensional boundary theory, including finite temperature effects.

Findings

Stable AdS_{13} x S^{13} solution found.

Suggests existence of a 12D boundary CFT with SO(14) symmetry.

Calculated glueball masses in AdS black hole backgrounds.

Abstract

We search for a possible bosonic (i.e. non-supersymmetric) string/gauge theory correspondence by using IIB and 0B strings as a guide. Our construction is based on the low-energy bosonic string effective action modified by an extra form flux. The closed string tachyon can be stabilyzed if the AdS scale L does not exceed certain critical value, L<L_c. We argue that the extra form may be generated as a soliton from 3-string junctions, similarly to the known non-perturbative (Jackiw-Rebbi-'t Hooft-Hasenfratz) mechanism in gauge theories. The stable AdS_{13} x S^{13} solution is found, which apparently implies the existence of a 12-dimensional AdS-boundary conformal field theory with the SO(14) global symmetry in the large N 't Hooft limit. We also generalize the conjectured AdS/CFT duality to finite temperature, and calculate the `glueball' masses from the dilaton wave equation in the AdS black hole background, in various spacetime dimensions.
